This invention relates to' the driving of dowelsiin-heels and is in "the nature of an 1mprovement onthe machine of Patent 1,595,547

of Aug. 10,1926.

iTheobjects of thisin'vention are to simpli-j and improve on the machine of sa d patent, rendering" thesame more positlve in its action and at the same time less fatiguing- 0n the operator; to adapt the machine to the 7 driving of inclineddowels; to providesimple indicating or signal mechanism for notifying ithe operator'whenthe dowel isproperly ,seated in the heel and to improve themachine other part-icularsyiasflwill hereinafter apear.

i 1 i The drawings" accompanying and forming part of this specification illustrate one practical commercial embodimentof the inventi'on, \vherei'n the objects set forth areatillustrationis primarily way of disclosure and that the"physic al strueture may vary all within the broad scope of the claims.

Fig.' 1 is abroken side elevation ofone commercial embodiment of the ,machine; Fig. 2'is a broken top plan view of the same; *Fig. 3 is a. fragmentary part vertical sec tional View as takenon substantially the perspective view illustrating the heel with theinclined dowel seated therein.

Referring particularly to Figs. 1 will be seen that the machine comprises in general an anvil or. rest 5 for supportingthe 5 heel 6 with the bore7 therein in line with the guideway 8 in the bed of theimachineY-an'd drive plunger. 9 carried '1 by a slide "10 and 1 operating to drive the dowelf ll out of said way into the bore in the heel i The dowels preferablyare'supported inia suitable guidechute'orhopper 12, so as to.

drop oneby one into the guideway .9. An

automatic cutofi sli de 13 maybe provided at '1 the foot of the hopper as in the patent re ferred to to cut ofi"and segregate the dowel in the guideway from the supply ofdowels being fed down by the hopper.
